The present double-hung metal window construction comprises a windowcasing or frame A arranged for vertical sliding upper and lower sashes Band C, respectively. The window casing or frame A comprises a headmember 1, two jamb members 2 and a sill member 3. The head member 1comprises a metal member having a substantially fiat main body portionprovided along its outside edge with a depending ornamental molding 4which constitutes the inside stop for the top rail of the upper sash B.The combined ornamental molding and stop 4 is provided on its undersidewith a flat face 5 to which a screen slide (not shown) may be bolted.The ornamental stop is made hollow and is provided along its inner wallwith an opening 6 whereby access may be had to the interior of saidstop, thereby permitting the nuts of the securing bolts to be readilyinserted within and removed from the recess in the hollow stops. Thehead member 1 is also provided along its outside margin with an upwardlyand outwardly extending top flange 7 which forms a key for a suitablecaulkingcmaterial 8 for sealing the joint between the outside edge ofthe head member and brickwork located thereabove. The inside edge of thehead member is also provided with an upstanding flange 9, similar to theoutside flange 7 thereof, which constitutes a seat for caul ing material10 and a guide for fixing the lower face of the plaster 11.

Each of the metal jamb members 2 of the window frame comprises asubstantially flat main body portion 12 provided at its outside marginwith a hollow inwardly extending ornamental molding 13, which is similarto the outside molding 4 of the head member and constitutes the insidestop for the adjacent side rail of the upper sash B and a seat for ascreen slide. Each jamb member 2 is also provided adjacent to its insideand outside edges with longitudinally extending flanges which projectfrom the outer face of the main body portion of the j amb and form theside walls of a sash weight box. The outer wall of the sash weight boxis formed by a sheet metal cover plate 15 which is provided midway ofthe side walls 14 of said box with an inwardly extending rib 16 whichdivides the box in two compartments. The flanges 14 of the j amb memberwhich form the side walls of the sash pulley box are each providedadjacent to the main body portion of said jamb member with anoutstanding rib or flange 17 which extends parallel to the bodyportionof the jamb member but is spaced therefrom far enough to form a key forcaulking material 18. The flanges 17 also serve as guides for locatingthe inner faces of the brickwork or plaster at the sides of the windowframe.

The sill'member 3 of the window frame comprises a main body portion 19,which slopes downwardly towards the outer edge of the window frame toprovide fordrainage, an upwardly ofli'set portion 20 located below thelower sash, and an inside marginal portion offset above said lastmentioned offset portion to form a hollow ornamental rib or molding 21which constitutes an outside stop for the bottom rail of the lower sash.As shown-in the drawings, the rib 21 is provided at the inside edgeofthe sill member with a key for caulking material 22; and the inclinedbody portion 19 of said sill member is provided along its inside marginwith a supporting flange 23 and along its outside margin with asupporting flange 24, which cooperates with a depending flange 25 on theoutside edge of said body portion to form a key for caulking material26.

Each of the j amb members 2 of the window frame A is provided with aninside molding or stop 27 comprising a metal strip of substantiallychannel-shaped cross-section arranged with its inner side flange inabutting relation to the flat main body portion of the jamb and havingits web portion extended inwardly beyond the inner face of said innerflange to form an overhanging flange portion 28. The outer flange of theinside stop 27 is provided with an inwardly extending lateral flangeadapted to form a shoulder 29 which bears against the inside edge of themain body portion of the jamb member. The marginal portion of the outerflange of the inside stop is flared outwardly to form an ornamentalmolding 30 adapted to conceal the caulking material 18. The inside stop27 is secured to the jamb member 2 by screws 31, which extendhorizontally through open: ings provided therefor in the web of saidstop and are threaded through the threaded bores of bushings 32 thathave a drive fit in openings provided therefor in the main body portionof said jamb. The bushings 32 are provided at one end with stop collarsor flanges 33, which bear against the outer face of the jamb; and theexterior surfaces of the cylindrical body portions of said bushings areknurled or otherwise roughened to retain them within the openings inwhich they are driven. Each of the j amb members is also provided with aparting strip 34 of substantially T-shaped section which isarranged withits web seated in a groove or channel provided therefor-in the'innersurface of the main body portion of the jamb member and with its side orhead flanges spaced inwardly from said jamb in the plane of the innerfaces of the inside and outside stops 13 and 27, respectively, thereof.The parting strip is secured to the jamb member by means of screws 35whichpass through .the web portion of said strip and are threaded intothe threaded bores of knurled bushings 32 similar to the bushings forthe fastening screws 31 for the inside stops 27. The inside stop 36 andparting strips for the head member 1 of the window frame A areof thesame size and shape as the inside stops 27 for the jamb members 2;andlikewise, the parting strip 37 for said head member has the same sizeand shape as the parting strips 34 for said jamb member. The partingstrips 34 and the inside stops for the head memher are secured to thehead member in the same manner in which the parting strips and stops forthe jamb members are secured thereto The metal frame members 38, whichform the top, bottom and side rails of the upper and lower sashes, areof substantially channel-shaped section, each of these memberscomprising side marginal flanges connected by a web which is providedalong its upper corner with a flange or abutment which forms a seat forthe window pane 39. The

pane 39 is set in puttyv 40 that is held in posit1on by means of glazinstrips 41 which fit the inner edges of t e sash frame members 38 withone flange in abutting relation to the inner face of said pane. Theglazing strips 41 are removably secured to the frame members of thesashes by means of screws 42. At the corners of the sashes the adjacentends of the channel-shaped frame members 38 are disposed in'overlappedrelation;

, along its inside margin with an upstanding that is, the end portion ofone frame member extends across the adjacent end of the other framemember. The overlapped end portions of the frame members are rigidlysecured together at each corner of each sash by means of two cooperatingclamping blocks 43 and 44, respectively, mounted in the channels of saidframe members and rigidly secured flatwise to the web thereof by meansof screws.

As shown in Figs. 7 and 8 of the drawings, the lower portion of the siderail of the upper sash extends across the adjacent end of the bottomrail thereof and has its web portion cut awayopposite the channels insaid bottom rail. A block 43 is secured within the channel of the siderail and has a bifurcated lower end portion 45 disposed opposite the endof the channel in the bottom rail. A block 44 is mountedin the channelof the bottom rail with its outer end projecting beyond the end of saidrail and entered within the bifurcated lower end of the block 43 in theside rail. The portion of the block 44 that is straddled by thebifurcated lower end of'the block 43 has a beveledupper surface 46 whichslopes inwardly and downwardly from the outer end of said block, andcooperates with a similarly beveled'surface 47 on the portion of theblock 43 located thereabove. A screw 48 extends loosely through avertical hole provided therefor in the beveled end of the block 44 andis threaded into the block 43 located thereabove. With this arrangementof corner connection, tightening of the screw 48 causes the beveledfaces of the two blocks to be slid one, on the other and thus drawtogether the overlapped ends of the vertical and horizontal rails of thesash.

The frame member, which forms the lower rail of the upper sash B, hasits bottom closed by means of a plate 49 which is provided flange 50 andlikewise, the top of the frame member, which forms the top rail of thelower sash C, is closed by means of a cover plate 51, which is providedalong its outside margin with a downwardly extending flange 52 adaptedto overlap the upstanding flange 50 on the cover plate 49 for the bottomrail of the upper sash in the-closed position of said sashes.

The window is provided with a latch for automatically locking the sashes*B and C in closed position. As shown in Fig.2 of the drawings, saidlatch comprises a spring- .pressed bolt 53 which is slidable in alinedopenings in the side flanges of the top rail of the lower sash and'has abeveled inner end portion adapted to enter an opening 54 providedtherefor in the upstanding inner flange 50 of the bottom 7 closure plate49 for the lower rail of the upper sash in the closed position ofthe-two sashes. During the closing movement of the sashes the beveledend of the locking bolt 53 engages a beveled surface 55 at the upper endof the upstanding inner flange -50 of the closure late 49 for the bottomrail of the upper sas and is thus slid inwardly against the pressure ofthe spring to a position whereby it may be automatically engaged withthe hole 54 provided therefor in said flange when the sashes are closed.

Located within the metal boxes formed by the flanges 14 of the jambmembers 2 and the sheet metal cover plates 15 are sash weights 56 forcounterbalancin the weight of the sliding sashes B and The sash weights56 are suspended in the boxes by means of sash chains, cords or ribbons57, which pass over pulleys 58 journaled in brackets 59 mounted on thejamb members, through openings provided therefor in said jamb members,and thence downwardly in the runways formed by the parting strips andinside and outside stops to the sashes. As shown in Fig. 7 of thedrawings, the sash weight chains for the upper sash extend downwardlythrough the channels in the side rails thereof and are attached to thelower corners of the sash by inserting the endmost link of the chain ina notch provided therefor in the In order to prevent leakage of air anddustv between the jambs of the Window frame and the side rails of thesashes, metal weatherstrips 62 and'63 are mounted in the jambs betweenthe parting strips and the inside and outside stops. As shownin thedrawings, the strips have a snug fit between the opposing walls of theparting strip and stops and are held against the panes bythe overhangingflanges at the side edges of said parting strip and stops. Theweatherstrips 62 extend from the sill of the window frame to a pointopposite the meeting rails of the closed sashes; and the strips 63extend from the upper ends of the strips 62 to the head of said windowframe. Each of the strips 62 preferably comprises a web portion, whichbears flatwise against the inner face of the jamb between the stops andthe parting strip, and outstanding. side marginal flanges 64, which bearagainst the opposing side faces of said parting strip and stops and arebent inwardly towards each other, thence inwardly towards said web andthence outwardly to form longitudinal grooves or slideways 65 adapted toslidably receive the side flanges of the channel-shaped side rails ofthe sashes. Each of the weatherstrips 63 is also of chanfor the sideflanges of theside rails of the flanges bent to formgrooves or slideways66 sashes. The webof the strips 63, however, are pressed out between theslideways 66 to form a longitudinal chann straddle the sash chain. Asshown in the drawings, the exposed portions of the sash chains for thelower sash are concealed by means of the'longitudinal channels 67 of thestrips 63.. The channels 67 of the strips'63 for the upper sash alsostraddle the chains therefor, and serve to conceal the same when saidsash is lowered. Outside air is prevented from entering the room throughthe lower ends of the channels 67 of the strips for the upper sash bymeans of felt plugs 68, which are sleeved on the lower end of the sashchains and completely close the lower ends of said channels.

The joint'between the top rail of the upper sash B and the head member 1of the window frame A is sealed by means of a channelshaped metalWeatherstrip 69 arranged between the parting strip and the outside stopwith its web portion bearing flatwise against the bottom of the headmember and with its side flanges bearing against the opposmg faces ofsaid parting strip and said outside stop. As shown in the drawings, theside flanges of the head strip 69 are doubled-back on the inside-of thechannel to form resilient sealing flanges 70 adapted to. bear againstthe respective inside and outside faces of the top rail of the uppersash in the closed position thereof. 1 p

The joint between the bottomrail of the lower sash C and'the sill member3 of the window frame "A is sealed by means of a metal Weatherstrip 71comprising a web portion, {which rests on the upwardly offset por tion20 of said sill and is provided along its outside margin with adepending sealing flange 72 adapted to bear against the inner face ofthe outside flange of the channelshaped bottom rail of the lower sash inthe closed position therefor. The inside margin of the sill strip71 isprovided with an upstanding flange 73, which bears against the outsideface of the inside stop '21 of the sill and is thence rebent downwardlyand s aced far enough away from the outstanding ange to form a resilientsealing; flange 74, which bears against the inside face of the insideflange of the channel-shaped bottom rail of the lower sash in closedposition thereof. The web portion -'of the sill strip is firmly clamped.down upon the upwardly offset portion 20 of the sill by means of aclamping plate 75 secured in position by screws. I

The joint between the meeting rails of the upper and lower sashes ismade weatherproof anddustproof by means of a metal weatherstrip 76comprismg a flat body portion which is secured to the outside face ofthe upstanding outside flange of the channel-shaped e1 67 adaptedtoupper rail of the lower sash and has a rebent or doubled-back portionwhich forms a re silient sealing flange 77 adapted to bear against theupstanding flange 50 along the inside edge of the closure plate 49 forthe bot v and jamb members are rigidly secured together by means ofangles 78 having one flange secured to the side flanges 14 of the jambmembers and the other flange secured to the underside of the headmember. The adjacent ends of the head and jamb members are furthersecured together by means of an angle 7 8 of one flange bolted flatwiseto the main body portion of the j amb and the other flange secured tothe top flanges of the two side angles 78 by means of bolts 79 passingthrough said flanges and said head member. The sill member 3 extendsbeneath the lower ends of the 'amb members 2 and closes the lower ends]of t e sash weight boxes. The adjacent end portions of the sill and jambmembers are secured together by angles 80 having one flange secured tothe side flanges 14 of the j ambs and the other flange secured to thesloping body portion of the sill. The j ambs and sill members arefurther secured by means of an angle 81 having one flan e bolted to themain'body port-ion of the j am and the other flange rest ing on the twoside angles 80 and secured to the sill member. j

The hereinbefore described weatherstripped metal window has numerousadvantages. It reduces to a minimum the insash pulle s and chalns. framemembers of the same cross-sectional size and shape, thereby reducing toa mini- I v mum the "number of specially formed frame members requiredfor the window; and it provides a rigid corner construction for thesashes. It provides a caulking key that-is I v continuous throughout thesides, head and sill of the window'frame, and it enables the head andjamb strips to be attached-to the window without the use of fasteningdevices, such as bolts andscrews. It is noted as an important advantageof the foregoing co1 1-' struction that the jamb strips, in addition toperforming the functions of a'weatherstrip,

serve also to conceal the sash' chains and leys and constitute yieldableslideways for said sashes. v

Obviously, the construction hereinbefore described admits ofconsiderable modification; therefore, I do not wish to be limited to ithe precise arrangement shown and described.
